PLOW.

Specification of Letters Patent.

Patented Jan. 6,1914.

Application filed June 27, 1912. Serial No. 706,264.

To all whom it may concern Be it known that I, JOHN W. RICHARD- SON, acitizen of the United States, residing at Glenwood, in the county ofGuilford and State of North Carolina, have invented certain new anduseful Improvements in Flows; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in plows.

One object of the invention is to provide a plow having an improvedconstruction and arrangement of clevis whereby the draft devices may bereadily attached thereto and having means whereby said draft devices maybe adjusted to regulate the draft of the plow.

A further object is to provide a plow and clevis which will be simple,strong, durable and inexpensive in construction and to which may behitched any desired number of draft animals.

With these and other objects in view, the invention consists of certainnovel features of construction, and the combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings; Figure 1 is a side view of my improvedplow and clevis showing the hinge member of the latter in closedposition in full lines and in open position in dotted lines. Fig. 2 is aplan view of the same 5' Fig. 3 is a side view of the front end of theplow beam and clevis showing the hinge member of the latter closed butnot fastened; Fig. 4: is a horizontal sectional view on the line H ofFig. 3.

In the illustrative embodiment of the invention 1 represents a plow ofconventional design to which the improved clevis is adapted to bereadily attached.

As clearly shown in Fig. 3 the clevis 15 is constructed in such a mannerthat when the same is in a closed position with the lugs 14 thereonlocated between the heads 9 secured to the outer end of the beam 5, thefree looking end 16 of the clevis will be elevated in a yieldingposition above the upper surface of the beam, whereby the ring or band17 slidably mounted upon the beam is adapted for interlocking engagementwith the free end of the clevis.

In connection with the plow, I provide an improved construction andarrangement of clevis 7 comprising a pair of side plates 8 having theirouter ends enlarged to form substantially elliptical shaped heads 9. Theplates 8 are provided with bolt holes 10 adapted to receive bolts 11whereby the plates are secured to the opposite sides of the beam whenthe clevis is arranged in a vertical position or to the top and bottomof the beam when the clevis is arranged in a horizontal position.

The clevis is provided with a coupling member or lever 12 comprising abar constructed to conform to the shape of the head 9 and having itslower end pivotally secured between the plates 8 to a pivot bolt 13whereby said bar is permitted to swing forwardly and downwardly to anopen position to receive the attaching ring of the draft deviceof theplow. On the inner side of the bar or lever 12 are a series of inwardlyprojecting lugs 14, the ends of which pass between the heads 9 and forma series of spaces with which the ring of the draft device may beadjustably engaged and for regulating the draft of the plow.

The upper end of the bar or lever 12 is reduced to form a spring catch15 having thereon a beveled stop lug 16. When the bar or lever 12 is inclosed or operative position the spring latch 15 will be disposed abovethe top of the outer end of the plow beam and owing to'the resiliency ofthe catch will tend to spring outwardly from the beam. The end of thebar when thus constructed is fastened to the beam by a ring or band 17which is slidably mounted on the beam and is adapted to be slipped overthe catch 15 which is depressed while the ring is being forced from thelug 16 and which, after the ring has passed the lug will springoutwardly and engage the lug with the ring thereby preventing the latterfrom becoming casually disengaged from the end of thebar. By thusconstructing and arranging the bar or lever 12 it will be seen that whenit is desired to attach the draft device to the clevis or to adjust thedraft device thereon it is simply necessary to release the catch 15 andswing the bar or lever outwardly from the end or heads of the clevis.

While I have herein shown and described the clevis as being secured to aplow beam in a vertical position to provide a vertically adjustablesupport and attaching means for the draft device it is obvious that theclevis may be arranged in a horizontal position to permit of ahorizontaladjustment of the draft device and that the clevis may be applied toother implements or machines.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as claimed.

Having thus described my inventionjwhat I claim is; I

In combination with the forward end of a plow beam, of enlargedelliptical shaped heads forming a partof and attached to the oppositesides of the beam and projecting therefrom, a: olevis conforming to theshape of the heads the lower end of which is hingedly secured betweenthe heads, a plurality of lugs projecting from the inner curved surfaceof the clevisi and adapted to be located between said heads when theclevis is in a locked position to prevent lateral displacement of theclevis, the free end of the latter being projected over the beam andadapted for'contact therewith, said end terminating in a spring catchhaving a lug thereon, and a ringslidably moiinted upon the beam andadapted for detachable and interlocking engagementwith said free end ofthe clevis, whereby the yielding portion of the latter is bi ndi'nglybrought in contact with the beam and the sanie'secu'rely held anoperative position.

In testimony whereof Iha vehereun'to set my hand in presence'of twosubscribing wit nesss.
